The relays are not installed to make it possible to add high watt bulbs, that�s just a side attraction.  The main reason for adding the relays is that the headlamp circuit has too many resistance gouging devices in the path to the headlights.  Just go measure the voltage at your headlights without the relays, you will find it�s about 9.5v not 12 as it should be.  AND, since some of these resistance gouging items are switches with small contact points surrounded by plastic which melts when the contact points are overheated the switch fails.  Headlamp switch and ignition switch are the ones that normally fail.  So��the real reason for installing the headlight relays is to save those two switches from melting and to get more voltage to the headlights.  With my relay kit you will get 11.5v at the headlights.  To get the full 12v you need to redo all the OEM wiring with larger gauge wire, not really worth the trouble unless you like doing that sort of thing for the extra 1/2v.
